Corallum vasiform and pedicellate, tabulate, or frequently subvirgate when young. 

 Upper surface usually flattened or concave; under surface almost without any twigs or buds, 

 but provided with numerous verrucifonn or annular, often dilated coraUites. Vasiform 

 specimens sometimes attain a diameter of 1'2 m., and a height of 30 to 60 cm., pedicel 3 to 

 8 cm. thick. The main branches are reticulately coalescent, the meshes of the network 

 being 5 to 10 mm. wide. Branchlets on the upper surface more or less crowded, many are 

 short and acervato-proliferous ; length 1 to 2*5 cm., diameter 5 to 10 mm. ; but without the 

 radial corallites the majority are little broader than the axial corallite. Axial coraUites
